Whilst writing the tests for the upcoming Poetry support, I made a few changes to the overall package manager testing strategy (such as using a testing buildpack to verify that at build time the tools and env vars are configured correctly) - which I've split out of the later PRs for easier review.
In particular, the new testing buildpack added here is what helped me debug and locate this upstream lifecycle build time env vars bug (which could have broken some build scenarios when we switch to venvs shortly):
